I have a project that involves recording data from a device directly into a sql table.
I do very little processing in code before writing to sql server (2008 express by the way)
typically i use the sqlhelper class's ExecuteNoneQuery method and pass in a stored proc name and list of parameters that the SP expects.
This is very convenient, but i need a much faster way of doing this.
Thanks.
Is there a refactoring tool available for SQL (TSQL in particular). Is there any tool that can do automatic simplification of SQL?
I have a set of views where only the top two are used, and I'd like to refactor this into only two views, hence 10+ queries into two queries.
i have two pc's on my lan (one with "iis and a public ip) and another with(sql server and lan ip). How i can access to the sql server pc trough iis pc From a pc on the internet?
Is this equivalent to a LEFT JOIN?
SELECT DISTINCT a.name, b.name
FROM tableA a,
(SELECT DISTINCT name FROM tableB) as b
It seems as though there is no link between the two tables.
Is there an easier / more efficient way to write this?
Do some out there use stored procedures with linq to sql and why? should we use them ? their support is there in linq to sql . I am asking because i use to use it before my recent application
Hi,
I want to translate LINQ expression tree to SQL statement and I don't want to write my own code for this.
Example:
var query = from c in Customers
where c.Country == "UK" &&
c.City == "London"
select c);
To
SELECT ... FROM Customers AS c WHERE c.Country = "UK" AND c.City = "London"
I know DataContext.Log, but I want to use:
query.ToSqlStatementString()
Thanks

I have a SQL table it has more than 1000000 rows, and I need to select with the query as you can see below:
SELECT DISTINCT TOP (200) COUNT(1) AS COUNT, KEYWORD
FROM QUERIES WITH(NOLOCK)
WHERE KEYWORD LIKE '%Something%'
GROUP BY KEYWORD ORDER BY 'COUNT' DESC
Could you please tell me how can I optimize it to speed up the execution process? Thank you for useful answers.

Hi,
I recently contacted a web host regarding support for external database access to a Microsoft SQL Server database included in a package they offer. They replied saying that it is only possible with an SSH-tunnel.
Is it possible to connect to a SQL Server database in Visual Studio using an SSH-tunnel? It is important for me to be able to access the database from my local machine (for debugging, generating LINQ classes, editing tables, etc).
Or, how should I go about working with their database?
Hello, sorry for answer but how to enable TCP in SQL server 2005 express edition? I used configuration manager, find network configuration/protocols and there enabled TCP, after that I have restarted sql server service and tried installation of problematic software again (software which told me that TCP is not enabled) but I have the same problem :-(
i have a string like this
something = "something, something1, "something2, something else", something3"
i need it to be read into a table like this:
field1 = "something"
field2= "something2"
field3 = "something2, something else"
field4 = "something3"
please notice that the double quotes in the something string signified that the string inside the quotes is to be placed in one field
anyone know how to do this with an insert into statement or some other way? the answer can be purely sql or can be vba with sql.
thanks!
Hello,
We have observed that there seems to be a maximum number of ids/variables which one can pass in the IN clause of SQL as comma seperated values. To avoid this we are storing all the ids in a table and doing a SELECT within the IN clause. This however means extra database operations to store and retrieve ids. Is there any other way to use IN without SELECT?

hi,
i have a blog application were Post belongsTo Category and Category hasMany Post
Post can have a Category or not - in latter case NULL value is present in Post.category_id field.
Now i would like to have following category count with single SQL query
category|post_count
--------------
PHP | 2
JavaScript | 4
SomeOtherCat | 1
NULL | 3
The clue here is that i also want to count posts without category (NULL row above). Is it posibble with one SQL query?
for a table valued function in sql why cant we write sql statements inside begin and end tags like-
create function dbo.emptable()
returns Table
as
BEGIN --it throws an error
return (select id, name, salary from employee)
END
go
while in scalar valued function we can use these tags like
create function dbo.countemp()
returns int
as
begin
return (select count(*) from employee)
end
go
is there any specific rule where we should use BEGIN & END tags

I want to perform a 'SELECT' statement with a byte array (binary) parameter as a condition.
I tried to google it, but didn't find anything useful.
In general, I keep information of files in the database. one of the properties is the file's hash (binary).
I want to give a hash to the SELECT statement, and get all rows with the same hash value.
I have a query regarding my report, the report format is as under
**Date** **Received** **Closed** **Pending**
12/01/10 1000 900 100
12/02/10 2000 1000 1000
12/03/10 1500 1300 200
The above report shows the Help Desk tickets Received, Closed, Pending Count as date wise.
How can I create a dynamic SQL query to show above result?
Received Tickets is calculated on SubmitedDate
Closed Tickets is calculated on ClosedDate with status "Closed"
same for Pending Tickets whose status is "Pending".
Please provide me the idea or some sample SQL queries.
Hi,
I'm writing sql query to my SqlCommand, and some part of them looks like:
WHERE Path like N'+(select top 1 path from [Paths] where objectcode=@objectCode and objecttype=@objectType)+%' order by path desc,objecttype desc
I get no records , bu when I wrote the same in sql server 2005 i have plenty rows...
where path like (select top 1 path from [Paths] where objectcode='eg' and objecttype='0')+'%'
order by path desc
What's wrong ??
@objectType is 'eg'

But i want to know, if it is possible, to make it work with something like this:
Select A.a,A.b,A.a+A.b as c, (c*2)+A.d as d from Table
Thank you
Call me pedantic but is there a more elegant way to combine all those checks?
SELECT * FROM [TABLE1]
WHERE [path] = 'RECEIVE'
AND [src_ip] NOT LIKE '10.48.20.10'
AND [src_ip] NOT LIKE '0.%'
AND [src_ip] NOT LIKE '127.%'
ORDER BY [date],[time] DESC;
To something like this:
SELECT * FROM [TABLE1]
WHERE [path] = 'RECEIVE'
AND [src_ip] NOT LIKE IN ('10.48.20.10','0.%','127.%', .... )
ORDER BY [date],[time] DESC;
